She is obviously going through a hard time as it's obvious by her destructive behavior. Ouija board scares the hell out of me as i have had experiences with spiritual realms and would not want to welcome them on my own. This practices generally open the door but without a qualified healer there is no way to control what comes through. She needs help and you're a great friend, she's lucky to have you. hopefully she can snap out of it before it's to late. I used to suffer with PTSD, Anxiety & depression years ago. I tried all options to get better and seem to have been getting worst every year. My last straw was old traditional shamanic healing I received in Peru. Since that time I have never had a single symptom and live a very happy & fulfilled life. This process allowed me to face all my problems without the ability of my ego to judge, once I have worked through my underlying issues I felt as I was reborn again. It made me see that I was living in past in future and that I am missing out on the present moment and living my life. I wish her the best of luck and I hope that she stays away from Ouija board, if you are emotionally unstable negative spirit so to say can take you over and make matters WAAYYY worst. I know to some people this may sound off the wall, it did for me until I experienced for my self. I accomplished in 10 days what conventional therapy couldn't do in 10 years and for that I am believer.
